Description of problem: An update of RHEL 5.x to NSPR 4.9.1 is needed if we are to update NSS to 3.12.5 as has been proposed. This is to be shipped together with the next Mozilla update to stable version 10.0.6 scheduled for mid July.

This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux release. Product Management has
requested further review of this request by Red Hat Engineering, for
potential inclusion in a Red Hat Enterprise Linux release for currently
deployed products. This request is not yet committed for inclusion in
a release.

For the record: the changes made for the nspr 4.9.1 update
The bulk of the changes come as the result of uptream supplying us with the nspr.pc.in file. The rather tricky sed editing on our own copy in the %install section of nspr.spec isn no longer need. I still do some light patching.

I restored the top part of to the original nspr-config-pc.patch that patches nspr-congig which I had mistankey removed. Without it we would have had a multilib regression. The rpmdiff based test caught that.
